            ProcessUtils::escapeArgument((new PhpExecutableFinder)->find(false)),
            $this->host(),
            $this->port(),
            ProcessUtils::escapeArgument($this->laravel->basePath())
     );
}

didn't get this also

Answer 1

The -S argument starts a embedded web server from the php executable.

It is a small, not for production or public use suitable web server, primarily used for debugging or demonstrations.

The localhost:8000 part is of course the address which the server will use.

The -t argument lets you specify a directory for the webroot. In this case the public directory will be used as the root directory for the webserver.

All in all it is a very useful debugging and testing tool since you don't have to setup a whole Apache or nginx server.

But as mentioned above: It is not suitable for production or public use since it's not a fully fletched webserver like Apache!

Answer 2

It's creating a command for starting the server that comes built-in with PHP. The server runs at port 8000 and servers files from ./public directory.
